Overall, it has many functions and the mobile application is quite useful (so you don't have to remember all the commands). However, its major drawback is that it consumes a lot of battery. In my machine with a 6Ah battery (new battery), it has discharged in a week and a half of inactivity. Therefore, if you go on a trip for two weeks, you will either have to disable the alarm or you will come back to find the battery discharged. What I have noticed is that it consumes a lot of energy, especially the GPS, which is constantly on standby. Especially if for some reason the GPS signal is not good in the area where the machine is parked, it constantly works to find a better signal, consuming more energy. There is a silent mode which is something like "energy saving" but it doesn't do much.

The consumption in a state of calmness is ~ 20 milliamps.
This device, in order to destroy your battery, requires 6 months of engine inactivity,
but of course it charges the battery with movement, it charges itself. So no worries about consumption
